" Shell : somewhat squarely semiglobose, compressly umbili- 

 cated, rather thin, pallid horny, spire very small, sharp ; whorls 

 three to four, convex, irregularly striated in the direction of the 

 lines of growth, sometimes evanescently obscurely irregularly 

 ridged and malleated in the opposite direction ; extremely rapidly 

 enlarging, last whorl abruptly widely auricularly inflated ; aperture 

 very large, outer lip thinly expanded, coluuiella callously twisted,

216. Limnaea (Gulnaria) brevicauda (Sowerby). 



Limncea (Gulnarid} brevicauda (Sowerbv), Con. Icon., Limn.. 

 sp. 105 ; H. & T., C. I., pi. 158, fig. 7. 



Original description : Shell obliquely tortuous, pale horn, 

 veutrico^e ; spire short, acuminated ; whorls three, small ; last 

 whorl much inflated, rather short, excavated behiud the columella, 

 aperture expanded, anteriorly subacuminated ; columellar fold 

 prominent, spirally tortuous. 



From the figure in the ' Conchologia Indica' the dimensions 

 would seem to be about as follows: Alt. 21, diam. maj. 17 mm. 

 It is probably a form of L. auricularia, Linn. 



Hob. Kashmir ( W. Blanford). 



Sowerby's specimen was said to be from Australia, but this was 

 undoubtedly an error.

Reeve, in his paper describing the shell, seems to think that it 

 is closely related to L. pereger, the common European form, an
